I got a crummy gearbox on my huasheng (honda 4 stroke clone) and it squeals louder than the engine roars. The engine sounds awesome. Probably doesn't have the same long term reliability as the honda but it's still nice. Anyhow I was thinking of getting the stage 3 gearbox from bicycle-engines.com to replace my 50 cent figure eight gearbox. Currently my gearbox will slow my coasting speed down to about eight miles an hour, maybe 10 on downhill. I don't even need breaks. Would the stage 3 gearbox solve the sound issue and the slow coasting issue?
